Fujitsu announces technology for future hard drive capacity expansion

Fujitsu of America announced another advancement in its research of magnetic recording. Using patterned media technology, Fujitsu was able to achieve a one-dimensional array nanohole pattern with a 25 nanometer pitch. This process could one day enable one terabit per square inch recording on HDDs. Fujitsu also revealed a new development involving perpendicular magnetic recording read/write operation on random patterned media. With this technology, the soft underlayer is used as the PMR media, another important milestone.

A density of one terabit per square inch is about five times greater than the current drive technology on the market. Applying a one terabit areal density figure to today’s drive sizes would give us 3.5” drives capable of storing 5TB or 2.5” notebook drives holding 1.5TB.

Fujitsu first announced innovations with patterned media recording in June 2005. At that time, advancements were made with the introduction of a process to pre-pit aluminum media, resulting in nanoholes with an extremely dense and ordered structure. In addition, a technique called land/groove texturing allowed for the creation of discrete tracks in which the nanoholes could be formed. This progress in patterned media has enabled the development of high capacity hard disk drives, especially in smaller form factors.

This progress in patterned media recording closely follows the November 2006 Fujitsu announcement regarding the optical element being developed for thermal assisted recording, another promising advancement for future capacity increases.

I have 1.5 terabyte of space with about 1.3 used up in video, music, photos and game downloads. MS wouldn't be coming out with Windows Home server for the average Joe if only a small percentage of users were using less than 200 gigs of space.

exactly. with the way things are headed consumers are going to be relying on an htpc type setup and once some of these new movie download services come into play average joes really will need that kind of space.

As long as DRM doesn't kill or control all our options and freedoms like the media companies want it to.

Agreed. I have a 320 GB HDD, with 100 gigs of that split up for OS's the remaining 200 GiB are about 1/2 full. And that's because I regularly end up backing up my media onto DVDs and deleting it. If I didn't I could easily fill up my HDD. So more storage for less is always a good thing - it's like money, you can never have too much.

This is why I asked what % of people. I doubt most of you are average users. So I wonder how much the average person uses.

Also, if the home user has a 1TB disk in their Windows Home Server, how do they back that up in case it crashes? Don't the larger disk sizes only create more problems when it comes to backing up? I don't think the avg user edits raw video footage. If they are editing video, more than likely it would be compressed i would think. Same thing with photos.

I mean, take a 200GB drive. HD video using WMV is about 8mbps (or 1MBps). So 130GB for video(~36hrs),20GB for photos (@ 5MB per photo that would give you about 4000), 40GB for music (230 CD's @ 320kbps), and 10 gb for OS.

The avg user i don't think is a gamer (at least not PC gamer)

I just wished they would put more focus on speed instead of size. It's like Intel back when it was trying to get the Ghz as high as possible. Thankfully, AMD made them reconsider.
